I'm totally new to FLUENT. I had a very newbie question in specifying the pressure values to the fan characteristic curve [using the Lumped parameter model].

From the user manual of FLUENT I found that - "All pressures that are specified and all pressures computed or reported by FLUENT are gauge pressures" and also that Absolute pressure = Operating pressure + gauge pressure.

So could some one please tell me whether the pressure values that are specified for the characteristic curves of the fan are gauge pressures (or) absolute pressures
